Antibiotic susceptibility of staphylococci isolated from labeo rohita sold in burla fish market, orissa
(Asian Fisheries Society, 2009) Sahoo, R.S.; Sahu, J.; Prasad, M.M.
Screening of commercial sold freshwater Labeo rohita revealed that the staphylococcal count decreased from one to two log cycles/g upon washing the fish. The fish samples harboured more number of staphylococci in edible meat portion than in guts. The microscopic, biochemical and oxidative fermentations tests of the isolates by conventional and rapid detection methods revealed that they are Staphylococcus haemolyticus, S. auricularius and S. caseolyticus. When the isolates were compared with 45 different antibiotics the results varied from susceptible to resistant in comparison with American Type Culture Collection cultures. In comparison to Clinical Laboratory Standards Institute isolates both the staphylococcal test cultures were resistant to penicillin (G) and vancomycin. With other antibiotics viz., Pristinamycin, Ticarcillin/Clavulanic acid, Gatifloxacin, Clindamycin, Clarithromycin, Levofloxacin, Linezolid, Cefeprime, Erythromycin, Streptomycin, Fosfomycin, and Piperacillin/Tazobactam the results varied from intermediate to sensitive.
